Y. As shown in said drawings, the implement consists' preferably .ofour essential parts or elements, namely, a pair of operating handles or levers 1 and 2, the knotter 3 and the gripper 4.- The two levers referred tol are of channel or Usection, and are bowed in opposite directions, soA as'toit 'the Ahand of the operator and aiford an easy grip; they. are pivotally connected together at their lower ends to forma V'by means of arem'ovable 'pin or bolt 5 which is` passed .through 'alihing perforations 'in said ends and isnornallyheld against withdrawal by a suitable spring clip 6, here shown asin theform of a forked plate, the jaws 7 produced at one end 'of the plate by the formationof a slot therein engaging the notched erdv 8 of the pin, while the opposite end of 'i said'plate is provided with a tongue 9 that' lis received in a perforation inthe lever 1. The free-end Vot the lever 1 is formed'with a Vrearwardly-curved f guard v10, and that of the lever 2 with. a cylindrical .barrel 11 to which the knot-ter is detachablyconnected.

Thejknotter elementpreferably comprises a' split sleeve or head 12 fitted upon the reduced neck '13 of the barrel 11, a carrier 121 for the bill 15, and an element 16 for actuating the movable part Vor ,member of the bill," as hereinafter described.' The carrier, which is depicted in' detail in Fig.y 8,v includes, acylindrical 'upper portion' 17, a downwardly tapered peripherally-toothed lower' portion ,18 and-an intermediate cylin- .d rical portion or' collar 19 of somewhat greater diameterthan the portions. 17 and 18, the lower end of' the toothed portion 18 .being fformed withy 'a reduced 'journal 20 which is received in a bearing opening 21` in q-therjbottom of the barrel.A vThe actuating element 'lis 'in the form of a sleeve whose' lower portion -iitsiinfthe space between the par'tsl vand'17, and4 restspupon the upper face -oflcolla'r 19'; theupper wall ofthis eley ment i'sform'e'd with an open-ended eccentricallylocatedv cam"ring 22. The head or sleeve"12,at the point where it vvis split,'is`

provided: with outstanding perforated ears 23 which are orcedtowardeach other, in

the `usual manner, by, a clamping screw 24,

so as to hold the sleeve in place upon the' barrel (neck. The bill 15 comprisesa pair of counterpart shafts whose upper porof said shafts. The severing plate is provided at'its up er end with the usual sharpened jaw 3Q, w ich co-acts with the -jaws 26,\ and its tower or wing portion 60 is formed with ahook 33 which extends across and over the upper 'portion of the cam ring 22.-

Means is lrovided for. rotating the cartIlie billl, to Actuate the latter andv the 'severing plate, the independent movement of saidplate bein effected, as. will beunderstood, through t e` agency of the cani ring and the hook 3B.A ySuch means, in the present instance, compi'iseslan arcuate rack .34 which is secured at one end to lever l, and projects at its opposite end through an opening in barrel 1l into kengagement with, the teeth 18 formed ."on the' carriage. To permit the full movement of therack, the opening just referred to extends completely through the barrel, 'and the latter is )rovded ut one side with an arcuate guard housing 35 which is arranged in alineinent with the rack and which said rack enters completely when the levers are forced'togethcr, so as to prevent it from coming into contact with the hand or lingers of the op erator, the said levers being normally separatedby a suitable spring A36 whose arms bear against them... It. will be apparent, therefore, that when the implement is gripped, the two levers will be moved toward each other, and the meshing of the vprojects toward lever 1 and is formed with a curved slot 38 having oneend thereof enlarged. l

The gripper clement 4, which serves to clamp the ends'of the threads in place during the knotting and severing operations. and to withdraw the tied threads from the knetter after the conclusion ofthe latter op- -`eration, preferably consists -of a series of [three juxtaposed levers 39, 40 and 41, the

outer levers 39 and. 41 being of counterpart construction and provided at their upper ends with laterally-curved bills 42 which are fastened together by a rivet 43. At the inner ends .of these bills, the levers 39 and 41 are slotted, asvat 44, the slots alining and producing a passage across which the curved' is..v

end or beak'45 of the central lever 40 moves, when that levei` is actuated. Adjacent their lower terminals, the gripper levers are formed with alinlng perforations 46 through which a pivot! bolt 47 is passed, the threaded inner end of said bolt being fitted in an,

opening in ,the lower portion of barrel 11,

.the gripper being -so disposed that. the bills 42 move forward and backward past the enlarged end of the lip slpt 38. At their e'xtreme lower ends, the outer levers 39 and 41 are provided with elongated slots 48 arid 49, t

and the central lever with a lateral pin 50, the shank of said pin passing throu vh'the slot 48, while its head extends intot e slot' 49, as shown in Figs. 1 and 3. Lever 41 is also provided with a lateral pin 51 which extends through`a slot 52 and an opening lower terminals thereof and vthe pivot openings 46;y (slee Fig.9); the pin 5]; is designed to fit snuglyT in openin the shank and head of pin .50 are designed to move freely in openings 48 and 49, thus providing for a movement of lever 40 relapor- y 53, but to Y haveplay in slot 52, and,` inv ike manner,

tive to levers 39 and 41. Lever` 39 is finally provided with aslot v54 located between openings 46 and 48, said slot having engaged therein the bent upper end of one arm of a ,spring 55 whose other arm bears against' lever spring 55 serves to hold the gripper normally inoperative position. i

In order to 'operate thegripper, there is provided an element which, in the construction illustrated, is constituted by a cam plate 5G secured to lever 1.. Said plate, as shown in Fig. 11, is formed with an-outwardlycurved slot 57 and with a forwardly-curved larm 5.8, vthe latter terminating in anlupsbentlinger or shoulder 59. The location of this plate with respectto pins 50 and 51 such ILS that when the levers 1 and 2 are forced toi gether said pins will successively enter slot 5l and cause. Ifirst, a lroclfring movement-of lever40 relative to levers 39 and 41 to move the beak 45 ofsaid lever 40 across passage 44. and, second, a bodily rocking movement .of the entire .grio ier. 5 Durinfr this o )erat, l ra tion,.the forward pin 50 travels along the upper edge of arm 5S and across slot 57, until it strikes against the upper end of the curved rear wall of saidslot.

continues, pin 50 is caused to enter into and As the cloS- l. ing movement of the main levers l and 2 travel down the slot, therebycausing the' above-mentioned independent movement of lever 40 and, subse uently, a slow bodily rocking movement o the gripper, (toward -the left, with respect'to FigsLl and 3). As

this rocking'movement of the gripper continues, the rear pinl reaches Athe upper end of slot 57 andsince this pin is located above l "and slightly to one side of piny 5 0, its 'entrancento said slot will cause the last half of the rocking movement of the gripper to take place comparatively rapidly. In the normal osition of the gripper, the passage 44 lies directly at the side ofthe slot 38, and for this reason the ends of the threads to be tied together are initially passed through both sald slot and said passage.

The complete operation of closing, movement ofthe main'leve'rs being depicted in Figs. 14 to 21, and the several steps in the formation ofthe knot in Figs'.v

41 5, to rotate counter-clockwise. This movement of the bill causes its nose to engage the threads, as depicted in Figs. 14 and 18, and, as the movement continues, to form the loop' in said threads indicated in Figs. 1.5,'

19 and 23. The hook 32 on the severing plate 28 is, during'the 4first part of this movement, traveling on the lower part of the cam ring 22, and thejaw 32 on said plate is disposed, 'in consequence, Wholly within the space between the two jaws 26; but during the second part thereof, as the billassures the positionshown in Figs. 15'

and 19, said hook reaches the high part of the cam, and the severing plate'is rocked,

with the result that jaw 32 moves upwardly out of said space. the third position, depicted in Figs. 16and 20,`the then elevated severing jaw extends across the left-hand portion of the threads, and is about to descend and cut the latter.

' At the same time, the initial movement of the gripper' takes place, and the right-hand Dort-ion of the threads is clamped in passage 44 by the actionof'beak 45 on the central gripper lever 40, that portion ot said threads being, also, carried forward bythe rocking movement ofthe gripper due to Vthe entrance ot' pin 50 into the slot 57 in cam plate 56. Then the bill'leaves the 'position shown in Figs. 16l and 20, hook 33 again rides on the lowportion ofthe cam` ring, causing jaw 32 to descend and sever the threadsslightly to the left of the loop.

the ldevice is as follows, the various positions assumed by the dltferent parts during the effective, or

"When the bill. reaches4 the loop into the space vbetween the vjaws 26 drawn from `the nose thereof by the gripper and the clamped ends are drawn through the loop, as depicted in Fig. 24,thus com pletingthe fori ationl of the knot. All parts are then in .the tion shown in Figs. 17
